Running Weblogic in Cluster mode on Win2K Pro

Question

Hi :
          I am running WL5.1 (sp8) on Win2K Pro, Is there any limitation that I cannot
          run Weblogic as Clustered in Win2k Pro ??.
          and how to setup Multicast IP Address ?. I tried with the default 237.0.0.1
          (using it with -D option to start the server) and other MultiCastIPs too I
          am having some problems :
          Note : I dont have any weblogic cluster / other applications that use the
          above MIP.
          =====================
          C:\weblogic>java utils.MulticastTest -n server111 -a 237.0.0.1
          ***** WARNING ***** ***** WARNING ***** ***** WARNING *****
          This utility should NOT be run on the same multicast address as a running
          WLAS cluster.
          Pausing for 5 seconds prior to starting test.
          Starting test. Hit any key to abort
          Set up to send and receive on Multicast on Address 237.0.0.1, on port 7001
          Will send a sequenced message under the name server111 every 2 seconds.
          Will also inform console every 600 seconds if no messages received
          New Neighbor server111 found on message number 1
          I (server111) sent message num 1
          java.net.SocketException: socket closed
          at java.net.PlainDatagramSocketImpl.receive(Native Method)
          at java.net.DatagramSocket.receive(DatagramSocket.java:392)
          at utils.MulticastTest$Receiver.run(MulticastTest.java, Compiled
          Code)
          I (server111) sent message num 2
          can anyone help me understand what the above problem is all about ?
          thanks
          Balaji.
